SUMMARY:EVSplitting: An Efficient and Visually Consistent Splitting Algori
 thm for 3D Gaussian Splatting
DESCRIPTION:Technical Papers\n\nQi-Yuan Feng, Geng-Chen Cao, Hao-Xiang Che
 n, Qun-Ce Xu, and Tai-Jiang Mu (BNRist, Department of Computer Science and
  Technology, Tsinghua University); Ralph Martin (School of Computer Scienc
 e and Informatics, Cardiff University); and Shi-Min Hu (BNRist, Department
  of Computer Science and Technology, Tsinghua University)\n\nThis paper pr
 esents EVSplitting, an efficient and visually consistent splitting algorit
 hm for 3D Gaussian Splatting (3DGS). It is designed to make operating 3DGS
  as easy and effective as other 3D explicit representations, readily for i
 ndustrial productions. The challenges of above target are: 1) The huge num
 ber and complex attributes of 3DGS make it tough to explicitly operate on 
 3DGS in a real-time and learning-free manner; 2) The visual effect of 3DGS
  is very difficult to maintain during explicit operations and 3) The aniso
 tropism of Gaussian always leads to blurs and artifacts. As far as we know
 , no prior work can address these challenges well. In this work, we introd
 uce a direct and efficient 3DGS splitting algorithm to solve them. Specifi
 cally, we formulate the 3DGS splitting as two minimization problems that a
 im to ensure visual consistency and reduce Gaussian overflow across bounda
 ry (splitting plane), respectively. Firstly, we impose conservations on th
 e zero-, first- and second-order moments of the weighted Gaussian distribu
 tion to guarantee visual consistency. Secondly, we reduce the boundary ove
 rflow with a special constraint on the aforementioned conservations. With 
 these conservations and constraints, we derive a closed-form solution for 
 the 3DGS splitting problem. This yields an easy-to-implement, plug-and-pla
 y, efficient and fundamental tool, benefiting various downstream applicati
 ons of 3DGS.\n\nRegistration Category: Full Access, Full Access Supporter\
